Re: [Freeswitch-users] mod_fifo and early media

Hi, thanks for your answer. I'm not a developper, but will look at that with someone in my team. What I'm currently planning to do (if possible), and submit as a patch for mod_fifo : Add a parameter to make mod_fifo manage two modes : 1. Normal mode, where the A-Leg gets answered (200 OK). 2. "Early media" mode, where the A-Leg is pre-answered, and kept in early media mode, until the B-Leg answers. The A-leg is then (automatically) answered when the B-Leg answers. Does it make sense ?

How to enable IPv6?
by Charles Yu 25 Nov '16

25 Nov '16

Hi, We want to use Freeswitch at IPv6 environment. How to do it? I saw there's a global variable "local_ip_v6". I think I need to change the default global domain variable ( at vars.xml ) as "local_ip_v6" and other module configs that use global variable "local_ip_v4". Are these right? Thanks in advance, Charles

mod_vlc playback hangup issue
by Anonim Stefan 23 Nov '16

23 Nov '16

Hi, I'm trying to playback a .wav using mod_vlc (.wav obtained via maryTTS). Dialplan extension looks like this: <extension name="tts"> <condition field="destination_number" expression="^tts$"> <action application="sleep" data="500"/> <action application="answer"/> <action application="sleep" data="1000"/> <action application="log" data="INFO before"/> <action application="playback" data="shout:// 172.16.36.67:59125/process?INPUT_TYPE=TEXT&INPUT_TEXT=${tts_src_data}&LOCALE=en_US&VOICE=cmu-slt-hsmm&OUTPUT_TYPE=AUDIO&AUDIO=WAVE "/> <action application="log" data="INFO after"/> <action application="hangup"/> </condition> </extension> The .wav gets played correctly with [1] Freeswitch log output. The problem is that after the file ends, the channel never hangup(i.e. show channels won't decrease), even after I end call. Actually, I won't receive 200OK for my BYE, as seen in the attached picture. I am using FreeSWITCH version: 1.6.12-20-b91a0a6~64bit (-20-b91a0a6 64bit). Is this a bug ? Thank you, Stefan [1] http://pastebin.com/Q364uHvp

Bridge an incoming call to an external SIP address
by Cato Gonzalez 23 Nov '16

23 Nov '16

Hi everyone, I am trying to get FS to route inbound calls to an outside sip provider but I am getting the call hung up on the FS side just upon the first or second ring on the B-leg. The diaplan action being executed is: <action application="bridge" data="sofia/internal/ XXX(a)sip.linphone.org"/> I have a softphone registered to this provider sip.linphone.org and it works well when calling XXX from some other IP phone. FS reports this in the logs: [DEBUG] switch_ivr_originate.c:1274 Raw Codec Activation Success L16@48000hz 1 channel 20ms [DEBUG] switch_core_codec.c:221 sofia/internal/ anonymous(a)webrtc.sip.mydomain.co Push codec L16:100 [DEBUG] switch_ivr_originate.c:1343 Play Ringback Tone [%(2000,4000,440,480)] [DEBUG] sofia.c:6760 Channel sofia/internal/anonymous(a)webrtc.sip.mydomain.co entering state [terminated][500] [NOTICE] sofia.c:7779 Hangup sofia/internal/anonymous(a)webrtc.sip.mydomain.co [CS_EXECUTE] [NORMAL_TEMPORARY_FAILURE] [DEBUG] switch_core_codec.c:246 sofia/internal/ anonymous(a)webrtc.sip.mydomain.co Restore previous codec opus:116. [NOTICE] switch_ivr_originate.c:3523 Hangup sofia/external/ XXX(a)sip.linphone.org [CS_CONSUME_MEDIA] [ORIGINATOR_CANCEL] Result is the same if I try to call any other sip destination. I appreciate any input anyone may give: have been working on this for a week already. Thanks, Cato

freeswitch sending '481 Call Does Not Exist' in return of BYE
by devang nathwani 23 Nov '16

23 Nov '16

Hello, Here are the sip traces of two legs leg1 UAC -> proxy -> media leg2 media -> proxy -> provider leg1 http://pastebin.com/G0jnF75t leg2 http://pastebin.com/299dZyN4 from leg1, when freeswitch(media) is sending back 480 temporarily unavailable after 183 session progress, UAC is sending ack and bye, now in return freeswitch is sending '481 Call Does Not Exist' my question is why? why freeswitch is sending 481 in return of ack and bye? here, 11.23.16.12 is UAC 11.23.16.13 is Opensips(Proxy) 11.23.16.16 is Freeswitch(Media) Thanks, Devang Nathwani

uuid_getvar / uuid_setvar Safety
by Colin Morelli 22 Nov '16

22 Nov '16

Hey all, This should hopefully be a very simple question. If I have a variable in one channel that I want to copy to another (these are unrelated, un-bridged channels) is it safe to just do, for example uuid_setvar some_var ${uuid_getvar other-call-id some_var} (from the dialplan)? Is there a better alternative? Without being an expert in how the variable expansion works, I want to make sure this would work for all possible values of the var, and I won't be caught off-guard with buffer size issues, separator issues, etc. Thanks in advance, Colin
